Insecticide

Q. I have ash trees on my property that are doing poorly and haven't been healthy for the last few years. Do I have Emerald Ash Borer?

A. Ash trees can be afflicted by many different disease and insect problems, such as anthracnose, verticillium wilt, ash flower gall, rust, ash yellows, and borers. Early infestations of Emerald Ash Borer are very difficult to detect.
